My invention relates to hair curlers and more particularly to the typeof hand operated curlers which are designed to form a curl and support ahair pin for the purpose of grasping said curl and maintaining itsformation.

As far as I am aware, the efucient hair curlers now known areconstructed so as to necessitate the following steps:

A. Positioning a hair pin on the curler subsequent actuation.

B. Applying the curler to the hair so as to grasp a strand thereof.

0. Forming the curl:

D. Actuating either the formed curl or the hair pin so as to effect theunion between the two:

E. Releasing the grasp of the curler on the hair strand and F. Holdingthe curl and hair pin with one hand while withdrawing the curler withthe other.

This procedure forms one curl. It is repeated to form others.

While the method outlined is not unduly involved it must be noted thatthe action most often takes place at the rear of the headwhere the userdoes not have visual access and that the operation therefor presentspractical difficulties.

It is the principal object of the present invention to simplify theprocedure to such anextent that most of the steps hereinabove outlinedare either eliminated or at least automatically accomplished by a singlemotion.

Another object of my invention is to provide a curler which carries itsown hairpin supply in a convenient, simple and efficient magazine sothat a pin'may be fed from said magazine to the formed curl.

Another object of my invention is to provide a curler wherein the usualmandrel about which the hair is wound embodies means to reduce thethickness of such mandrel when the curl is completed so that thecombined curl and pin may easily be slid ofi the end of the mandrel.

Another object of my invention is to provide novel and automatic meansfor releasing the grasp of the curler on the formed curl, this purposebeing accomplished without the necessity of actuating the clip initiallyused to connect the curler to the hair strand.

A further object of my invention is to provide a curler of suchconstruction as to simultaneously and automatically supply a hair pin toa formed curl, reduce the effective thickness of the mandrel for thepurpose herein above set forth, and release the grasp of the curler onthe hair for strand, the above steps being accomplished by one simplemovement.

It is also an object of the present invention to effect all of the aboveresults with a simplified construction of the device itself so thatmanufacturing costs are decreased and economies realized,

Other objects of my invention will be apparent from the followingdescription it being understood that the above general statements of theobjects of my invention is intended to explain and not to limit it inany manner.

In the drawings, I represents the mandrel about which the hair strand His Wound, the mandrel. 1 comprising the mandrel jaws la and lb. The jawlb is connected as by solder to the plug 2 while the jaw I a is movablein respect to the housing 3v and is connected to the jaw lb by thespring 4. Thespring 4 has its ends connected to the respective innerfaces of the mandrel jaws.

A pivot Ic movably connects the inner end of the movable jaw Ia to thetubular member 9. The mandrel jaw la is further provided with aprotuberance Id for a purpose to be hereinafter described.

The tubular member 9 is a hollow cylindrical 7 vided with an integralflanged sleeve I and a partial boss 8.

The housing 3 encloses the parts hereinabove described and is secured bythe bolt 3a to the flanged portion of sleeve 1. Clamp 5 is pivotallyconnected to the inner wall of the housing 3 as by the hinge 62) formedfrom cars depending from said inner wall, and clamp 5 is actuated by thefingerpiece 8. The clamp 5 is normally urged into engaging position withthe movable jaw Ia by means of the spring 6a which is connected at oneend to the tubular member 9 and which communicates with the flngerpiece6 through an opening in the housing 3.

The housing 3, tubular member 9 and sleeve I are all formed with anintercommunicating slot I2 which slot functions as the ejection chamberfor the hairpins B.

The hairpins B are disposed around the tubular member 9 and their shankshave their free ends located on either side of the sleeve I, while theclosed ends thereof abut the boss 8. Since the hairpins comprise shankswhich in the normal clamping position abut each other, the sleeve 1functions as a support for the hairpins also serving to maintain themproperly alined.

A spring actuated follower I is disposed around and rotatably supportedby the tubular member 9. Said follower I9 is formed with a flange IIwhich, in response to the spring I5, bears against the hairpin supplyand is designed to urge the foremost hairpin into the ejection chamberor slot I2. The flange Ii has a slotted end III), the sleeve I looselyfitting on said slot.

The follower I0 is further provided with a slot to accommodate the boss8 of the tubular member 9 as seen in Fig. 8. The boss 8 extends from theslot I2 on the member 9, or just enough to accommodate the hair pinsupply.

As shown in Fig. 1, the follower I3 is formed with a closed end I I (1.having two openings formed therethrough.' A cap I4 is rotatablyconnected to the plug 2 by means of the bolt I8, and pins I'I, enteringthe two openings formed in the closed end of the follower Ill, securesaid follower II] to the knurled cap I4 so that both the cap I4 and thefollower IIl may rotate relative to the plug 2 as well as the remainderof the device.

The cap I l and follower II] are connected by the spring I to thehousing 3, the pin Ila, of the cap I4 operating as one terminal of thespring I5 and the end wall 16a of the housing 3 operating as the otherterminal by abutting the end It of said spring.

A slide I3a having the fingerpiece I3 is located in the slot I2 and isslidably retained therein. The slide I3a operates from the normalposition wherein it abuts the closed end of the follower I0 shown inFig. l, to the extended position wherein the hairpin has been totallyejected, shown in Fig. 2. The slide I3a is further formed with a concaveactuating end I31) and an inelined cam edge I30 for a purpose to behereinafter described.

Secured to the rounded wall of the tubular member 9 is the floor I9which supports thereon the hairpin spreader I911. The spreader I Socomprises a single piece of twisted spring blade stock and is connectedat one end 2| to the floor I9 while the other end is bent to provide theraised end 20. The end 20 of the spreader I9a is free and is furtherprovided with an inclined edge 2%.

My invention operates in the following manner:

The hairpins B, as shown in Fig. 5, are inserted into the housing 3through the slot 22, the shanks of the hairpins embracing the sleeve 7.While the supply of hairpins is being thus inserted around the tubularmember 9, the knurled cap I4 is turned and held against the action ofthe spring I5 so that flange II of the follower I ll does not actagainst the hairpins and interfere with the loading of the magazine.

When all the hairpins have been inserted the cap I4 is released and theflange I I driven by the spring I5, bears against the adjacent or lasthairpin in the magazine so that the foremost hairpin is forced into theslot I2. The wall of the slot I2 in the housing 3 adjacent the spreaderI9a is formed with a flange 3d to function as a stop for the hairpins soas to insure the proper positioning of the hairpin in the slot I2.Furthermore, since the sleeve I is formed with a slot, comprising theslot I2, when the foremost hairpin has been urged into the slot I2 bythe action of the flange II], the shank ends of the hairpin are shiftedto a position wherein said shank ends embrace the spreader I9a as seenin Fig. 9. Thus the hairpin is wholly disposed in the slot I2 andsupported at its shank ends by the spreader Illa.

At this point, the curler is ready for use and theflngerpiece 6 isdepressed to admit a hair strand and grasp the same by the clamp 5. Theentire device is now rotated so that a curl of hair H, as seen in Fig. 1is formed around the mandrel I. When this curl has been completed, theslide I311 is actuated by the operators finger and the following actionresults:

The concave edge I3b of the slider I3a bears against the closed end ofthe hairpin and forces the same along the slot I2. Traveling, as theshanks do over the bent portion 20a of the spreader Isa, they arediverged as they emerge at the inner end of the slot I2. The lower shanktravels under the cut-away portion 5a of the clamp 5 so as to slideunder the formed curl H while the upper shank being spread embraces theperiphery of the curl. This action is shown in Fig. 10 and Fig. 2.

When the closed end of the hairpin reaches the inclined edge 2% of thespreader I9a, it forces the spreader I9a downwards or laterally of thedevice. The spreader, being of spring stock, the central portion thereoffunctions as a spring'between the connecting end 2| and the freespreading end 20.

This lateral displacement of the spreader I9a clears the slot I2 so thatthe hairpin can wholly emerge from the housing 3. This action isillustrated in Fig. 10 wherein the hairpin B is shown in longitudinalsection to reveal the disposition of the lower shank thereof.

When the slide I3a approaches the limit of its travel, the inclined edgeI30 thereof bears against the protuberance Id of the movable jaw Ia ofthe mandrel I. This pressure depresses the movable jaw Ia against theaction of the spring 4. As a result thereof, the clamp 5, which hasremained stationary in relation to the housing 3 and the fixed mandreljaw lb, is now spaced from the, mandrel so that the curl of hair H isautomatically released from the grasp of the clamp 5, and the reduceddiameter of the mandrel enables the device to be withdrawn withoutdisturbing'the formation of the curl. In Fig. 2, R denotes the decreasedthickness of the mandrel I permitting the release of the formed andpinned curl so that the device may be easily withdrawn for the'n'extoperation.

It will be noted that the radial construction of the magazine permitsthe rotation of the entire device in forming the curl and provides amost simple yet eifective mechanism. It will be jiurther noted that thesimple movement in operating the slide l3a achieves the followingresults:

The hairpin is actuated to clamp the formed curl, the effectivethickness or diameter of the mandrel is reduced to permit unrestrictedwithdrawal and the release of the clamp 5 is automatically accomplished.

When the slide 13a is in the position shown in Fig. 2, the succeedinghairpin will not be urged into the slot I2 by the follower I!) becausethe shank ends abut against the slide 13a and the spring I5 is too weakto overcome this resistance. This impediment at the free ends of thehairpin serve to keep the closed end thereof clear of the slot until theslide is retracted to its normal position whereupon, the passage beingclear, the succeeding hairpin will be urged into the slot I2 and theoperations may be repeated on another hair strand.

I have shown a preferred embodiment of my invention but it is obviousthat numerous and very substantial changes may be made without departingfrom its spirit.

I claim:

1. A hair curling device comprising a hollow handle portion, a mandrelaround which hair is adapted to be wound supported by and laterally ofsaid handle portion, a sleeve located within said handle portion, asupply of hair pins radially disposed around said sleeve the shanks ofsaid hair pins embracing said sleeve so as to travel thereabout and aslide adapted to individually actuate said hair pins from within saidhandle portion to a position of engagement with a curl formed aroundsaid mandrel.
